Dave, for the sake of having the conversation in a single place, I'm
responding to your comment on bugzilla here. I tried your package which did
not fix the issue. Since I somehow forgot to add it in the actual case, for
reference here is the stack trace:

After installing your package, I noticed one major difference between yours
and the upstream git that I built. Since I am not using the same Fedora
configure flags as you had asked, mine is not building with
--with-gallium-drivers which is apparently not a default. My mesa build
only included libradeon_dri.so and *not* libradeonsi_dri.so, which is what
actually fixed the problem. So I removed your and my packages, and
reinstalled the latest from the yum repository, then removed
libradeonsi_dri.so. This also fixes the issue, so the problem is obviously
with the gallium drivers and not necessarily the current version of mesa. I
will try one more time rebuilding the latest from git with gallium drivers
enabled and see if the issue still exists upstream.
